Must purchase the Snorkel kit to work with the Dial-A-Jet, part #1094540001.

Dial-A-Jet is a completely external jetting system that delivers maximum horsepower from any engine at any temperature or altitude. Dial-A-Jet improves throttle response and fuel mileage. It works well with stock or modified engines, standard or high performance air boxes and exhaust systems.

Works by taking fuel from the float bowl and mixing it with air creating emulsified fuel. The emulsified fuel is delivered to the engine instantly and acts as an intermediate circuit until the heavy wet fuel from the other circuits catch up. The emulsified fuel charge, fills in the lean spots between the poorly atomized fuel molecules from other jetting circuits eliminating lean spots. The lightweight fuel charge follows the path of least resistance. This gives you a consistent, even fuel supply at all engine RPMs.

Dial-A-Jet allows you to re-jet your entire engine in minutes. Allows you to tune each cylinder individually for maximum performance. Improves fuel efficiency 10% to 20% or more.

For only 3 easy payments of ......

Jeremiah in IN – Machine this part was bought for: 1986 HONDA ATC 350X

Comments On Sep 10, 2013:Product installed pretty easily, but somehow I believe it to be one of those corny items you buy that's not all its cracked up to be. Bike still ran ok, but it ran ok before the install. If you are one of those people that buys crap from those weird info-mercials then this is right up your ally. BUT WAIT THERES MORE......just kidding that's all I got.

Amazing results

Mandy in WY – Machine this part was bought for: 1996 YAMAHA YZ250

Comments On Jul 30, 2013:after making small jet adjustments and getting everthing tuned i noticed a major differance at how smooth the powerband kicked in after installing the dial a jet. i started riding at 4365 ft elevation in wyomings northern hills and went past 9000ft in its rocky mountains without ever adjusting anything but the dial a jet and never fouled a plug. the dial a jet worked great and i recommend this product to anyone tired of changing jets on 2 strokes. ive rode over 40 hours so far with the dial a jet and never had to do anything but fill up with gas. amazing product!!!

Something to TAME the BEAST!

Comments On Mar 12, 2013:I have this system on all four of my quads, 2 Z-400s , Artic Cat DVX 300 and the Beast a KFX-700. I mainly run in the sand so we push em hard! The KFX-700 has been the hardest to jet as it has 2 carbs and is very thirsty. As stated this system WILL require some jetting changes but it is all for the better- now all i have to do to go from 4800ft run down to 2600ft run or at 800ft is turn the dial. The system does add power as it acts like an on command fuel injection when your motor needs it only, like when climbing a 500ft dune-killer.

Dial a Jet

Ken in GA

Comments On Oct 02, 2011:Easy installation. I can tell the mid range is much better. My z400 pulls alot harder. Highly recommended. Must buy snorkle kit. Why not included ?

Seems flawed to me

MONTY in AB

Comments On Jun 05, 2011:In it's design it takes unfiltered air and mixes it with fuel and put the UNFILTERED air into the engine. They do offer the snorkel kit which they recommend for off road use...but a small piece of open cell foam doesn't seem like a great filter. Also depending on your carbs/intake system it may be VERY tricky to install. My Banshee was not as nice and easy as it would install on my Scrambler. I like the priciple...not the actual product. I eventually opted to NOT install the kit on my Banshee. I ride the foothills and felt the adjustability would be nice...but ultimately introducing UNFILTERED air into my engine seemed like engine rebuilds waiting to happen.

way better than jetting all the time

DAVID in OH

Comments On May 06, 2008:have a 660 raptor and it works great! this makes life simple since have 2 carbs to jet. change jets initially and never touch carbs again. just turn the dial a jet. makes alot of difference in bottom snap. Now runs like injected 700s.

Excellent Jetting Alternative

Neal in AR

Comments On Mar 11, 2008:If you're upgrading your quad with a pipe and a high flow filter and you need to re-jet just skip ahead to the Dial-A-Jet. This adds a ton of throttle responce down low. It's so easy to install you'll swear you missed a step.

pretty good

WAYNE in CA

Comments On Feb 26, 2008:It works but i would have to say its not a complete replacement for a jet kit as it only allows for more fuel to be delivered and cannot lean out the fuel mixture so if you do a lot of higher altitude riding its useless, I run it in conjunction with a fmf jet kit and it works quite well.
